INSULATORQIBRACKET.

T all whom it may concern Be it known .that'I, FRANKA. Bowman,

a citizen of the United States, residing at Cerro Gorclo, in the county of Piatt and State of Illinois, have invented certain new and useful Improvements in Insulator- Brackets; and I do declare the following to be a full, clear, and exact description of theinvention, such as :will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lmprovements 1n insulator brackets.

One object of the invention is to provide an insulator brackethavingan improved construction and arrangement of attaching members by means of WlllClL the 'bracket when secured to a pole or other ob ect Wlll effectually resist all strain applied thereto through the wire connected therewith and which is particularly adapted for use-as a dead ending bracket, but may be em.-

ployed in any capacity or in any position where an ordinary insulator bracket is used.

Another object is to provide a bracket of this character which will be simple in con- 'struction and may be producedat very little if any greater cost than otherinsulator brackets now in use, and which are unreliable. t g 1 With these and other ob ects, 1n view, the

. invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed. I

In the accompanyingdrawings: Figure'l is a front view of the upper'end of a pole showingmy improved bracket secured thereto; Fig. 2 is a side view of the parts shown in Fig. 1; Fig. 3 is a horizontal sectional view of the bracket taken on the line 33 of Fig. 1; Fig. 4: is a perspective View of the bracket.

My improved bracket comprises'a main bar 1 having on its upper end, right angularly projecting bracing arms 2 which may be of any suitable shape to fit or engage the object to whichthe bracket is to be attached and which in the present instance are shown as being curved or of segmental form to eni gage the sides of a telegraph pole or similar The main bar or shank 1 and the object. arms may be of any sultable cross sectional shape and are preferably triangular as shown. The bar or shank 1 also preferably gradually decreases in thickness toward its Specification of Letters Patent. Pat

and provided with an aperture? to receive flattened and have formed therein apertures 4 adapted .to receive suitable fastening devices which areinserted therethr'ougha and together with the fastening devices inserted through the aperture. 3finthe bar 1 are' driven into the pole or other support to which thebracket is attached as shown. On the upper end of the bracket and at entedMay18,"1915. Application filed February 18, 1913. Seria1'No.749,1 27. 7 I

outer end and has its outer endffiattened the inner end of the bar or body 1 isformed a threaded finger 5 which is adapted to receive the insulator 6 which may be of the usual or any preferred construction. The

finger is slightly offset or deflected and projects at an oblique' angle from the upper end of the bracket and thus spaces the in.-

sulator from the pole or object to which.

the bracket is attached and holds the in? sulator in position to receive the wire which may be readily secured thereto in the usual v a I I By providing the'bracket 1 with curved 1 T f or any suitablemanner.

object engagingarms 2 'apertured at their ends it will, be seen that the bracket will 7 effectually resist any strain which may be applied thereto by the wire connected there with and it will be practically impossible to pull the bracket from its pole or support.

By reason of its peculiar construction and" its capacity for resisting great strains :the.

bracket is particularly adapted for holding great strain which is applied directly to the bracket. Because of the great strain ap plied to the dead ended wire it has been 6X7 i tremely difiicult to obtaina bracket orto fasten the same firmly enough to support such a wire or to receive the strain applied resist any strains whi'chmay be applied dead, ended wires which are subjected to thereto by a dead ended wire. or any other strain towhich thesame may be subjected in supporting telephone, telegraph or electric light circuit wires or'cables From the foregoing description taken lin connection'with the accompanying draw- Y ings, the construction and operation of the 7 invention will be readily 'understood without requiring a more'extended explanation.

Various changes in the form, proportion and theminor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is:

An insulator bracket comprising a semicircular arm for engagement with a support, the ends of said arm having apertures therein whereby to secure the same to the support, a depending shank formed integral with said arm midway of its ends, the inner face of said shank being arcuate in transverse section and tapered in thickness toward its lower outer end to conform to the outline of a support to be engaged thereby, the extreme lower end of said shank being also provided with an aperture whereby to secure the same to the support and a threaded insulator finger also formed integral with said semi-circular arm intermediate of its ends, said finger alining with the shank to form substantially a continuation of the latter and bent outwardly and upwardly with respect to the arm to facilitate the application to and removal of an insulator thereon.

In testimony whereof I have hereunto set my hand in presence oftwo subscribing witne'sses.
